There seems to be consensus among authors of iterative routines in R to issue control parameters to functions in lists with names like "control". Looking at the help page for 'lme' suggests its authors have followed that pattern. This is a question that would get a wider audience of knowledgeable minds regarding lme and cousins if it were directed to the sig-ME mailing list.
